Saskatchewan Premier Brad Wall is following through on a tax cut for parents that his party had promised in the campaign.

Wall has announced the extension of a provincial sales tax exemption on clothing for children up to 18 years old, up from 14, starting next week.

Voters returned Wall and his Saskatchewan Party to the legislature in Monday's election with a huge majority.

The Saskatchewan Party took 49 seats in the 58-seat legislature and nearly two-thirds of the popular vote.

The NDP took the other nine seats -- the lowest number the party has held since 1982.

Wall says the tax exemption will cost $1 million for the rest of this year and $3 million annually after that.
